Battle of the exhaust

**Jay4743** · 03-16-2012, 11:39 AM

As stated above it's about personal preference. I went with SLP Loudmouth lm1 despite all the mix reviews about it because I like loud and couldn't be happier with that choice. I take alot of 3 hour trips back to my hometown and it's mostly highway and the drone doesn't bother me one bit and thats with lt's and a ory now. But I like loud so thats probably why it doesn't bother me.

there is a web site where you can hear just about every combination of exhaust ie. stock manifolds/y/catback headers/y/catback blah blah blah...ls1sounds.com

I really didn't experience any rasp at all with the LMII with my stock manifolds. I did however have some along with drone at around 2200-2500RPM when I got my Kook's 1-7/8" headers and 3" Kook's ORY with the LMII.

LM1.

If you ever may do headers forget the LM1. The Borla can be completely opened up with stock manifolds and cats and closed up a little with headers and an off road Y pipe. The LM1 is awefull with headers and an off road Y. And I like loud.

I love my long tubes / loudmouth 1. Sounds like an animal.

You answered your own question.
I have the LM II and love it.

**ls1nightrider** · 03-24-2012, 01:40 PM

What brands would you say you get more hp?

**Guerrillakilla13** · 03-24-2012, 03:22 PM

I think they both sound great, but the Borla setup has adjustable restrictor plates on the passenger side exit pipe. This means you can adjust how much air bypasses the muffler and how loud you want it to be with a muffler on

LS1nightrider, I read somewhere that the borla gets the most horsepower out of all the brands. I could be wrong

**ls1nightrider** · 03-28-2012, 08:14 PM

Im trying to decide between the loudmouth or magnaflow.
Im leaning more on the LM

**jaydean21849** · 03-29-2012, 05:30 AM

Lm1. Love it

GMMG. They are pricey though

**cowstandmoto** · 04-13-2012, 04:20 AM

I run Loud Mouth II. And I like it. But when it gets used up, I'm going to try either Borla or Corsa.

**Justin D** · 04-14-2012, 04:30 AM

Run duals and you'll never have to make a decision again.

If you plan on keeping your stock manifolds, LM sounds great. If you plan on getting long tube headers to replace the stock manifolds at some point, I would suggest something like a Magnaflow instead.

I agree with you. I had a Flowmaster and it was 2 loud I now habe a Magnaflow and on the hgwy its great still loud but not crazy the Flowmaster was sic my buddy just installed headers with his Loudmouth and yiu can't even varry a Conversation in the car loll Good luck

My car with lts/ory/lm1 is stock like quiet driving under 1500 rpms in 4th gear. Not sure why you cant have a conversation in your buddys. Maybe I just have a high tolerance I just saw your 41. The older people around here think mine is loud.

Ouf that hurt lolll!!!! I remember being 20 and looking at 41 year old thinking they were old 2 lolll
He has an auto with 4:10's so 1500rpm at 70mph is not in his cards loll an you are right 20 years ago it was never loud enough and I lovvvve the sound of his car now, it sounds like a wild animal racing down the street but its way too loud for me and rolling in at midnight after a day at the track in a campground with 400 people They seem to be unappreciative of loud cars lolll

I have to agree that the car sounds amazing and my Flowmaster sounded amazing better than my Magnaflow but a wife and kids takes that loud exhaust out of my cards anyway :-) Good luck guy!
